Figure 5 is a transverse sectional view as taken along the line 5-5 of Figure 3; and

Figure 6 is a plan view of the single blank of cardboard or other sheet material of which the box is formed.

The essential feature of the present invention is best illustrated in Figures 2 and 3. The face viewable in Figures 2 and 3 is the top of the box as shown in Figure 2, this top of the box being substantially flat so as to facilitate stacking of a number of the boxes-one upon the other. The distortion which is shown in Figure 2 is substantially exaggerated when compared with that existing in the actual construction of the box. the distortion being resorted to for better illustration of the box construction. In this connection it will be noted that while the sealed flat top of the box includes therein the handle-forming elements referred to more specificall hereinafter, these elements are of such construction and relative arrangement that when disposed flatwise in the plane of the box top they form no such external pro- 2,693,310 Patented Nov; 2,; 1 954 2: jections as. might interfere. with -vertieal .stacking. of. the filled. and sealed boxes.

Moreover, it is.-importantto. noteth'a't. the handle.- forming elements are so incorporated-inth'etop closure flaps of the-.boxastcoplanar .elementsof'said flaps that sealing, of the. flaps; in; their superir'nposedrelation shown in Figures 2 .and15is readily, effected. through the use of .any'suitable fiapgsealing apparatus, either manually or automatically;operatedi Of fc'ourse, suchapparatus forms no part of: the present; invention and is accordingly neither shown nor'described herein.

Theboxxof'the present invention is madeof a single blank. ofsuitable.sheetcrnaterial.as? shown in Figure 6 of. the drawings; This" blank isdiecut andscoredas shown, the score lines beingflindicatedbv broken lines and thecuts beingindicatedby. full lines; In the blank the oblong portions 10 and.11.form the side Walls of the box, while the approximately'square portions 12 and 13 form the opposite 'end wallsiofthe'box. Integral with the lower edges of th'e side walls Hand 11 are the extensions 14 and15whichrespectivelyconstitute halfbottoms-for the box, which, when-the box is expanded into box form, are disposed incoplanar relation with their free edgesabuttinguto" conjointly form the full bottom of the box.- The extensions 16 and 17' which are integral wit-h'theylower edges of r the end "walls 12 and 13 form the customary inner bottom flaps against which the half-bottoms 14and'15"are adhesively secured.

The side -wall-10 is provided with an integral extension 18"constit'i1tinga-top closure-"flap for the'b'ox, this extension having at its outer edgea hand-hold flap 19 integraltherewith. Similarly; the-sidewall 11 is also provided with anintegral extension 20""constituting a second top closure flap which is "adapted" to-partially overlie the closure'flap -18 and form conjointlytherewith a fullclosure for the top' of the'box;- In addition, the top closure flap '20' isprovided withapair of laterally spaced coplanar 'sections 21"'2-1'between-which extends a second hand-hold' flap 22, the: latter being laterally defined by the slits ZS ZS Wh-ich separate the central hand-hold flap- 22""frorn the= laterally spaced sections 21"21. It -will he noted that the slits 23- 23 terminate iust sh'ort of the outer:edge 24 of th'e closure:flap 20 so as-to norrnally retain=the hand-hold flap 22in the plane oftheflap 2t'iiuntil such ti'me asmit is desired"to-raise the hand h'ol-d flap 22 out the -planeof-"th'e flap 20 and into handle forming position.

The h'and-hold fl'ap t 22" is suitably I apertured; as at' 25 while: the flap "19 is centrally -sl-it to 'provide a hand:- hold aperture-for registry with-the: aperture 25 when the flaps-19 and22 are superppsed flatwiseagainst one another; Preferably, the-hand-hole formed in the flap 19*is 'providedwith a reversely foldable tongue portion Z'G -Which is adapted to be-foldedsback asbest shown in Figure'S to-provide'arounddupperedge for'the handh'ole' formed by the registering" apertures of the. superimposed 'fiaps 19 'and 22.

Tliaside -wal-l portion 10 is' provided' alongits free edge witha securing flap 27 which is adapted to overlie and be secured to the vertically extending free edge of the end wall portion 13 of the blank, thereby providing an open-ended rectangular box construction having parallel end walls 12 and 13 and parallel side walls 10 and 11, the side walls being respectively provided with the top and bottom closure flaps hereinbefore described. The end walls, in addition to the bottom closure flaps 16 and 17, are respectively provided at their upper edges with top closure flaps 28 and 29, Which are adapted to be folded into coplanar relation just beneath the overlapping top closure flaps 18 and 20, as is most clearly shown in Figure 1.

In the manufacture of this box the blank of Figure 6 is initially expanded into substantially rectangular condition'with the overlap 27 glued or otherwise secured to the inner face of the end Wall 13. Thebottom closure flaps 16 and 17 are then 'inturned and the half-bottoms 14 and 15 are then adhesively secured to these flaps 16 and 17, thereby forming a sealed bottom for the box. In this expanded condition of the box, its top is wide open and it is thus adapted to be filled with the goods which it is designed to receive, following which filling operation the top closure flaps 28 and 29, integral with the upper edges of the end walls 12 and 13, are folded over the contents of the box. At this point the handhold portion 19 is turned back upon the closure flap 18 along the scored line 30 and the bottom face of said flap 18 is adhesively secured to the underlying flaps 28 and 29. The box is now in the condition shown in Figure 1 of the drawings.

Adhesive is now applied preferably to all of the bottom face of the closure flap 211 including the portions 2121 and 22 thereof, following which the flap 20 is pressed down and secured in position against the underlying surfaces of the flaps 28 and 29 and of the flap 18, which latter surfaces also may be adhesively coated as shown in Figure 1. The structure thus obtained is best illustrated in Figures 2 and 4 wherein it will be observed that the superimposed hand-hold portions 19 and 22 are adhesively secured together as a unit which is swingable out of the plane of the box top. This hand-hold unit formed of the eiernents 1.9 and 22 adhesively secured together is normally retained fiatwise in the plane of the top of the box by the readily separable connections 39-31) at the ends of the slits 2323 which separate the handhold portion 22 from the laterally spaced sections 21-21 of the top closure flap 20. Upon breaking open these connections 30-410, the hand-hold unit comprising the elements 1.9 and 20 is free to be swung upwardly about the score line 31 into the upright carrying position shown in Figures 3 and 5, the top of the box being then rnaintained in its sealed condition as shown.

It will be understood, of course, that the present invention is susceptible of various changes and modifications which may be made from time to time without departing from the general principles or real spirit of the invention, and it is accordingly intended to claim the same broadly as well as specifically as indicated by the appended claims.
